Therefore, the present utility model is not limited by the specific embodiments disclosed below.
[0015] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments, and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.
[0016] The following further elaborates on the specific embodiments of the present utility model in conjunction with the accompanying drawings.
[0017] It is given by Figures 1 to 5 including a cabinet body 1, a cabinet door 2 is hinged to the front end of the cabinet body 1, an air inlet hole 3 is opened at the rear end of the cabinet body 1, air outlet holes 4 are respectively opened at the left and right ends of the cabinet body 1, an intake fan 5 facing the air inlet hole 3 is provided at the rear side of the cabinet body 1, exhaust fans 6 corresponding to the positions of the air outlet holes 4 are respectively provided on the left and right sides inside the cabinet body 1, a rectangular accommodation groove 7 communicating with the air inlet hole 3 is opened at the rear side inside the cabinet body 1, a rotatable connecting plate 8 is provided in the accommodation groove 7, filter plates 9 capable of blocking the air inlet hole 3 are respectively provided at the upper and lower ends of the connecting plate 8, cleaning brushes 10 capable of contacting the filter plates 9 are respectively provided at the front and rear sides in the accommodation groove 7, the filter plates 9 are located between the two cleaning brushes 10, and a notch corresponding to the air inlet hole 3 is provided at the upper end of the cleaning brush 10.
[0018] In order to rotate the connecting plate 8, a rotating shaft 11 in the front-rear axial direction and rotatably connected to the cabinet body 1 is provided at the rear end of the connecting plate 8, and the rear end of the rotating shaft 11 penetrates through the cabinet body 1 and is coaxially and slidably connected with a rotating column 12.
[0019] In order to increase the sealing performance, rubber sealing rings 13 coaxial with the air inlet hole 3 are respectively provided at the front and rear sides in the accommodation groove 7, and the filter plates 9 are located between the two rubber sealing rings 13 and can contact them.
[0020] In order to facilitate the fixation of the rotating column 12, limiting holes 14 are respectively opened at the upper and lower sides of the rear end of the cabinet body 1, a limiting column 15 capable of being inserted into the limiting holes 14 is provided at the front end of the rotating column 12, and the rear end of the rotating shaft 11 is connected to the rotating column 12 through a spring 16.
[0021] In order to facilitate the collection of the dust swept down, a collection groove is opened at the left end of the cabinet body 1, a collection box 17 with an upward opening and located below the cleaning brush 10 is detachably connected in the collection groove, and a pull handle is provided at the left end of the collection box 17.
[0022] In order to facilitate use, an observation glass window and a door lock are provided on the cabinet door 2.
[0023] When the present utility model is in use, first, the electrical device is installed and placed in the cabinet body 1, then the cabinet door 2 is closed and the intake fan 5 and the exhaust fans 6 are turned on. The intake fan 5 rotates to suck the outside air into the interior of the cabinet body 1 through the air inlet hole 3. The sucked air passes through the filter plates 9 to filter the dust in the air and prevent it from entering the cabinet body 1 to damage the electronic components. At the same time, the two exhaust fans 6 rotate to extract the gas entering the cabinet body 1. The relatively low-temperature air entering the cabinet body 1 takes away the heat generated by the electronic components and is discharged from the cabinet body 1 through the exhaust fans. In this way, an air convection is formed to continuously take away the heat generated by the electronic components in the cabinet body 1 and prevent the temperature of the electronic components from being too high;
[0024] After using for a period of time, the filter plate 9 is covered with dust. At this time, turn off the intake fan 5 and the exhaust fan 6. The operator pulls the rotating column 12 backward. The rotating column 12 drives the limit column 15 to move backward on the rotating shaft 11. After moving backward for a certain distance, the limit column 15 disengages from the upper limit hole 14, releasing the fixed limit on the rotating shaft 11. At this time, rotate the rotating column 12 clockwise. The rotating column 12 drives the two filter plates 9 to rotate clockwise around the rotating shaft 11 through the connecting plate 8. After rotating a certain angle, the filter plate 9 covered with dust rotates between the two cleaning brushes 10 and continues to rotate. At this time, the two cleaning brushes 10 clean the surface of the filter plate 9. The dust washed away by the cleaning falls into the collection box 17 due to gravity. When rotated 180 degrees, the original lower filter plate 9 rotates to be located between the two rubber sealing rings 13 and corresponds to the position of the intake fan 5. Release the rotating column 12. The rotating column 12 moves forward due to the restoring force of the spring 16 forward, and then drives the limit column 15 to move forward. After the limit column 15 moves forward for a certain distance, it is inserted into the lower limit hole 14 to re-implement the fixed limit and prevent the connecting plate 8 from rotating. At this time, there is no dust on the filter plate 9. Turn on the exhaust fan 6 and the intake fan 5 to continue heat dissipation;
[0025] When the filter plate 9 is covered with dust again, repeat the above operation at this time, rotate the filter plate 9 cleaned by the cleaning brush 10 back to the position of the intake fan 5 again, and at the same time clean the filter plate 9 covered with dust again.
[0026] Compared with the prior art, the beneficial effects of the present utility model are as follows: The provided cabinet body, intake fan, exhaust fan, etc. can achieve the protection and heat dissipation of electronic components, prevent the electronic components from being damaged, and at the same time can quickly replace the filter plate without dust, and clean the filter plate covered with dust during the replacement for convenient next use. Compared with the traditional central cabinet, the filter plate can be quickly cleaned, preventing the filter plate from being blocked by dust and resulting in poor heat dissipation effect. This structure is simple, novel in concept, convenient to use, and has strong practicability.
[0027] It should be noted that according to the needs of implementation, each component described in the embodiments of the present utility model can be split into more components, or two or more components or parts of components can be combined into new components to achieve the purpose of the embodiments of the present utility model.
[0028] The above embodiments only express several implementation manners of the present utility model, and their descriptions are relatively specific and detailed, but should not be construed as limiting the patent scope of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model should be subject to the appended claims.
